A HLA Simulation Technology Overview

Modeling and Simulation (MS) of High Level Architecture (HLA) have become the standards of the Institute for Electrical and Electronic Engineers. A federate in the simulation system developed based on HLA can be implemented by modifying a legacy simulation or developing new one, but all the relations between models must embodied by the particular implementation of federates. This paper introduces the concept, main contents and fundamental criterions about HLA from theory and practice enclosing the problems about system modeling and simulation based on HLA in comparative detail, and presents one part of the frame of torpedo federation member simulation program codes written according to HLA standards, and indicates that the simulation programs written according to HLA standards are the developing directions for complex and large system simulation, especially are the developing directions for weapon system simulation. This paper has some reference values and guiding meanings for studying HLA standards.
